Descripción
This entry starts the discard service when required. This service is used as a debugging tool by setting up a listening socket which ignores the data it receives. The discard service is used as a debugging and measurement tool. It sets up a listening socket and ignores data that it receives. This is a /dev/null service and is obsolete. This can be used in DoS attacks and therefore, must be disabled. Audit: `lssrc -s inetd -l` must not list the service (count 0).
